Serial No. 627,636.

To all whom e' may concern Be it known that we, lVlLLIAiI BURLING,

to a modified form for discharging ashes through the side of a vessel, and to the form of the ash pipe nozzle and the ash valve.

The objects of our invention are to simplify the construction of the above mentioned ash dischargers, and to improve the efiicieney of the discharger by the location and design of the ash pipe nozzle, and to rovide a modified form of the dischargeror discharging through the side of the vessel, either above or below the water line.

Te have ascertained that the location and form ot' the ashA pipe nozzle has a great deal of infiuence upon the operation ofv the discharger, and we have determined, approximately, the shape and location best suited to secure the maximum vacuum in the ash pipe, with the minimum supply of water in the hydraulic stream.

The features of construction, combination andV arrangement of parts are illustrated in the accompanying drawings.

Figure 1 represents a sectional view of our ash discharger. Fig. 2 represents a sectional view of a modified form of ash valve, and Fig. @represents a sectional view at right angles to Fig. 2. Fig. 3 represents a sectional view of the rotating cylinder shown in Figs. 2 and 2E, and Fig. 3a shows a sectional view at right angles to Fig. 3. Fig. 4 represents an elevation of the complete mechanism at right angles to the view shown in Fig. 1. Fig. 5 represents a sectional view of an ash discharger constructed for discharging` through the side of the vessel above or beiow the water line, and Figs. 6 and 7 represent an end elevation and detailsview of the mechanism shown in Fig. 5, and Fig. 8 represents a transverse sectional view of a vessel, showing in elevation our ash discharger instailed therein and discharging below the water line and at one side.

Referring by numeral to the drawings: the numeral 1 denotes the ash hopper for receiving the ashes, 2 the casing of the ash valve, 3 the oscillating portion of the ash valve, 4 the ash pocket in the ash valve, 6 the lever for operating the ash valve, 7 a water connection for washing out the ash valve, 8 the pipe supplying the hydraulic stream to the ash discharger, 9 the ash pipe, 10 the nozzle of ash pipe, 22 the discharger casting, l1 the stop valve for closing off the sea when the discharger is not working, and 12 the sea connecting pipe.

In Fig. 2, which represents another form of ash valve the numeral 13 represents the hopper, 111 the rotating cylinder containing the ash pockets 15, which receive the ashes from the hopper and discharge them to the ash pipe; 1G represents a Water supply pipe for supplying Water to the pockets 15 when they reach the position for discharging to the ash pipe. The water passes through the hole 17 to the ports 18. The gears 19 and 20 are for rotating the cylinder 14 by means of hand or other power applied to the shaft 21.

Fig. 3 represents an enlarged view of the rotating ey inder 14 vwith the water connection 16, the hole 17 and the port 18 for supplying water to the pockets 15 when they are delivering to the ash pipe.

In Fig. 5, which represents a sectional view of the discharger arranged for dis'- charging through the side of the ship, above or below the water line, and Fig. 6, an elevation of the discharger, the number` 23 rep# rescnts the ash hopper, 24 the ash valve. casing, 25 the ash valve cylinder, 2G a shut oft' valve, 27 the discharger casting, 28 the nozzle of the ash pipe, 29 the annular opening for the hydraulic jet, 30 the discharge pipe, 31 a water nozzle which may be supplied either by the water from plpe 33, which supplies the hydraulic stream, as shown at Fig. 7, numeral 34, or by the independent pipe 32, through theport 35.

In Fig. 8, which 'represents the discharger installed in a vessel and discharging through the side, numeral 36 represents the hopper, 37 the ash valve, 38 the cutofi` valve, 39 thel discharger, 40 the discharge pipe, 41 a valve, l 4t2 the pump for supplying the hydraulic stream, 43A the water supply to the jet in lll@ the -ash pipe, 44 and 45 the ship structure, and 46 the. water line. y

The operation of the ash valve shown in Fig. l is as follows: rllhe hopper l is located so it is not dir ectly over or in line with the ash pipe 9, and to operate the valve the lever 6 is moved so the ash pocket 4 occupies the position under the hopper shown in dotted lines by numeral 5, and receives the ashes from the hopper 1.` After receiving the ashes the lever 6 is moved to the position shown in the drawing and t-he pocket '4 is moved to the position 3, in which yposition it delivers the ashes contained in the pocket to the ash pipe 9. In this position the water from the pipe 7 assists in clearing the'ashes from pocket 4. `When the pocket 4 occupies the position 5 the water from the pipe 7 discharges into the casing 2 and flowsfreely 20 Yto the ash pipe 9.

It will be seen from the drawings and the above description that the ash valve prevents the water from the sea from entering the vessel -at all times, incase the hydraulic pressure from the hydraulic pipe 8 decreases so the velocity pressure is not sufficient to prevent the outside waterfrom entering.

lVe have shown in Fig. 2 a-rotating ashl valve that consists of a cylinder 14 which is rotated by power applied Ito the shaft 21, and transmitted through the gears 20 and 19 to thel cylinder 14. The cylinder 14 contains ash pockets 15 which pass unden neath the hopper 13 and receive ashes from same. As the cylinder rotates the pockets pass over the ash pipe and discharge theashes to same. The water connection from pipe 16 enters the center of the rotating cylinder 14 and passes out through a single 4t;

pass over the ash pipe, -thus washing out the pockets. lt will be noted that the water can enter the ash pockets only through the hole 17 which is located above the ash pipe, and therefore the water enters the ash pocketsionly at this position.

We do not conine ourselves to the particular forms of ash valveshere illusrated, because there arev a large number of imple forms, some of which are better adapted to certain conditions of installation than others. rlhisv is illustrated by referring to ash valve shown in Fig. 1, which is adapted to the discharger which opens out of the bottom of the ship, because any long piece of iron or other material, that enters the pocket 4 will pass straight out through the ash pipe 9, which would not be the case if this ash valve was used on the horizontal discharger shown in lFig. 5, Sheet 2, because the long piece of iron or other material would lodge in the elbow. It is therefore desirable to use, on the horizontal discharger, the rotating form of ash valve shown in Figs. 2 and 9, which will not pass hole 17 to the ports 18 as the ash pocketsy -for-m and location of ash discharger nozzle,

and we wish to draw particular attentionI to the advantages of delivering the ashes to the hydraulic stream by a special nozzle and near the center and inthe direction of the How. ln the drawing the hydraulic stream enters the discharger casting 22 from the pipe 8 and the ash pipe 9 is carried down sol the nozzle 10 delivers lthe ashes inthe center of the hydraulic stream. The discharger casting 22 is arranged so that the stream flows around the ash pipe 9 before passing the nozzle 10. rlhis arrangement offers the least possible resistance to the stream at the point the ashes are delivered and produces the minimum losses due to. eddying eiect. The nozzle also delivers the ashes in the direction of the flow and near the center of the stream. The form of nozzle 10 is made conical by increasing the thickness of the metal, or otherwise, so the water passes by the ash pipe 9 in a stream of annular section converging after passing the nozzle l0, and forms a solid annular jet or stream of circular section. This form 100 of stream has no eddies and produces the maximum effect of vacuum in the ash pipe 9. The minimum quantity of water is required for operating. the discharger with this special form of nozzle. .fer to use a double tapered conical pipe 30 next to the nozzle for gradually reducing the velocity ot the discharging stream ofwater, thus avoiding the loss due to the shock from too rapid a change in the ve- 11o locity of theistream.

The discharger arranged for discharging the ashes through the side of the vessel, either above or below the water line, which we term the horizontal discharger, has the 115 ash pipe curved so that the nozzle 28, will deliver the ashes near the center of the hydraulic stream-and in the direction of the flow. rlhe water jet which Hows through the nozzle 31 assists to force the ashes 12o through the curved portion of the ash pipe and into the hydraulic stream. rlhe suction in the ash pipe caused by the low of the hydraulic stream past the nozzle 28 and through the annular opening 29 assists 125` lVe also pref stream, wherethey do not rub against the sides o the pipean'd are carried out with the-How of' the stream. This is a distinct advantage .over the `,forni of dischargers that forcefthe ashes through the ash pipe \vith -a solid jetot high velocity,` which f' causes the ashes to riib` against the di'si., charge pipe and results iii excessive wear.

^ "f ln ,ordertoiitain a jet of high'eiliciency for,operatingthedischarger, we use a partic'iilar-.ftlirii'iof'hydl-aulic pipe in conjunction with :uconical nozzle on the ash pipe. 'lhcr hydraulic.` pipe is Ispheroidal 1n shape i adjacent to theconical ash pipe nozzle, so

thestreain iscaused -to tiow toward the coiiical jnozzle atVv the point where the jet is vformed; this, in conjunction with the' parw31* 'iai r'lltlnl'fille.. A

lad 'the higlielliciency is essential to the ticiilar lform `.of nozzle used, causes the vstr earirto forni a converging annular jet.

after passing the conicalnozzle.v ()ui exl 'periiuents have 4demonstrated that the use 1 of a conical, discharge pipe 30` for confining the converging annularjet, adds greatly to theetiiciencyjof'fthedischarger. The conical i'" Yareniade Ltowconform to approximately thc discharge pipe and the converging water jet saine'jshapeand size, by adjusting the conical'noz'zle.' andthe adjacent spheroidal hydraulic pipe... The high efficiency, diie to the jetland the conical discharge pipe, makes,

Itwill be Aseen that we have provided a mechanism, with which it is possible to deliver'v the ashes into a flowing stream of `waterfwhich is under pressure, by carrying the ashpipe into the stream and causing the water to pass the ash pipe nozzle in a stream of annular section. ()ur devcenot only delivers the ashes to the tiowing stream,

but utilizes' the velocity of the stream to produce. a` suction in the ash pipe. The -suc- .tion thus produced by the stream of annular section flowing'passes the ash pipe nozzles,4 "55 .draws the 'ashes into the stream and they are carriedfoverboard withvthe Atliscliarging The water will not flow. hack into .the ash pipeand enter the vessel so long as the velocity Aof the stream yis maintained above a certain point., and it is therefore not 'necessary to provide an absolutely water tight ash valve as would'be the case if this arrangementcf ash pipe`were not used.
